Calculate the mass percentage of CaCO3(s) in the sample..
I don’t know how to handle this Chemistry question and need guidance.
A 0.450 g sample of impure CaCO3(s) is dissolved in 50.0 mL of 0.150 M HCl(aq).
The equation for the reaction is
The excess HCl(aq)
is titrated by
6.75 mL of
0.125 M NaOH(aq)
Calculate the mass percentage of CaCO3(s)
in the sample.
